back to my question, does anyone make a set of 1+ mm valves that can be used with the stock lifter set up for 99+ and vvt heads? Would it be better of contacting the manufacturer and asking for custom length valves?

Look up SI Valves, I run them in my 99 head. Was around $200 for the set IIRC

I did a general "si valves" and theres tons of stuff, its to generic, any other keyword to narrow it down? is SI the manufacturer? or did the come off a civic si? Did you post the info or was it someone else? I just bought a set of Manley race valves which where more then the super techs, if they arent going to work for my 99 head i may end up flipping them. I tried pming you but your box is full.

thanks

Ignoring all the advice, I went ahead and got some shorter shims online. So far so good. 200 miles later and no clatter or other reolated problems.
Now on to the next problem: Overheating. It wasn't doing that before the engine-swap. Oh well.....

Your 'too long' valves could be an excuse to slap some regrind cam with mad lift (modifying base circle from 36 to 33mm needs to be compensated by... longer valves! or slimer shims)
Oh btw i seems too late on this... No idea for overheating though...
